Question

For 9 innings, Boman has an average of 75 runs. In the tenth inning, he scores 100 runs, thus increasing his average . His new average is​

Answer 1

Answer = Rs. 76.5

Total score for 9 innings is 75×9 = 675

Total score after 10th innings = 675 + 100 = 775

So, average = 775 / 10 = 77.5

Answer 2

Total score for 65 innings = 65*9 = 585

Total score after 10th innings = 585 + 200 = 785

So, the new average is 785/10 = 78.5

So, the increment is of 13.5
